This was a great thread on my old car forum. The basic premise is for this to be a one stop thread for cheap mods. $20 and under mods only. Basically im a cheap bastard and I know others are too.

(if this is a repeat thread, then forgive me i searched first)

I can start her off:

Made my own shorty antenna. Use two pliers to pry off the ball on the top of the stock antenna. Cut to desired length, and reattach ball with epoxy. I also painted mine black. Best part about this one is it was free (I had the epoxy and paint sitting in my garage, but even if you don't they are still cheap)

Next:
I also bought a shorty antenna online, it was only $15. The reason I made mine though is the reception is spotty where I live (its mountainy here, I need a longer one [thats what she said]) Heres a pic of the one i bought.

Lastly:
Plastidipped my wheels. Self explanatory and you can see a pic in my signature. Cost ~$20 for all four wheels.
